| Popis: | The first heteroleptic NiII diselenophosphinates and thioselenophosphinates, [Ni(Se2PR2)2L2] and {Ni[Se(S)PR2]2L2} (L = pyridine and 1-vinylimidazole), have been synthesized in high yield by the one-pot reaction of the ammonium salts NH4[Se2PR2] or NH4[Se(S)PR2] with NiBr2 (CH2Cl2/EtOH, rt, 10 min), followed by the addition of the N-heterocyclic ligands. In the solid state, all the complexes exist as mononuclear species, in which the coordination polyhedron of the Ni atom is a compressed octahedron formed by four chalcogen atoms (S and/or Se) of two bidentate chelating [R2PSe2] or [R2P(S)Se] ligands and two nitrogen atoms of two pyridine or 1-vinylimidazole molecules, arranged in trans-positions. |
